United States Patent 6 FINGER RING WITH A SHANK HAVING SET ATTACHING,GEM SUPPORTING PRONGS Raymond G. Lutrario, Providence, R. I., assignorto Uncas Manufacturing Company, a corporation of Rhode IslandApplication February 15, 1955, Serial No. 488,263 2 Claims. (Cl.63-15.7)

This invention relates to a finger ring, particularly a finger ringhaving a box type setting for a gem and/or the like.

Finger rings of this general type are usually made of separate elementswhich are secured to each other as by solder. The soldering operationrequires skilled labor and is also a disagreeable operation in that theworker frequently suffers burns in performing the operation.

An object of the invention is to provide a finger ring of the above typeso constructed as to completely eliminate the above soldering operation.

A more specific object of the invention is to provide a finger ringwherein the gem setting portion will be secured to the ring shank byclamping the walls of the setting between portions of the ring shank.

Another object is to provide a construction in which the gem willadditionally function to bind the ring shank and gem setting to eachother.

With these and other objects in view, the invention consists of certainnovel features of constructions as will be more fully described andparticularly pointed out in the appended claims.

In the accompany drawings:

Figure 1 is a front elevation of a finger ring embodying my invention;

Figure 2 is a similar view but showing the gem setting portion of thering in section;

Figure 3 is a perspective view of the gem setting;

Figure 4 is a perspective view of the ring shank; and

Figure 5 is an elevational view partially in section showing the gemsetting and ring shank in assembled relation prior to the ends of thering shank being secured to the walls of the setting.

The shank of the finger ring according to the present invention is madein the form of a split annulus with the ends flattened so as to form ashoulder. The gem setting is of a box type which may be of any desiredshape, as by way of example generally rectangular, and has oppositelyaligned openings pierced through opposite walls adjacent to the bottomwall of the setting. The flattened end portion of the ring shank isinserted in said openings with the said shoulders providing abutments toengage the edges of the openings. The flattened portions extend withinthe setting and are bent to clench the same against the adjacent wallsto clamp and secure the setting between the said shoulders.

Referring to the drawing for a more detailed description of theinvention, designates a finger ring having a shank 11 to which issecured a gem setting 12 for a gem 13 which is secured in position byfingers or prongs 14 which are bent over the gem in the known manner.

The shank 11 is made in one piece of suitable strip stock having thedesired shape in cross section. The end portions of the strip areflattened as at 15 so as to form shoulders 16, and the strip is bentcircularly so as to form a split annulus (see Figure 4). The setting 12is of the box type and may be made of any of various shapes appropriateto a ring setting. As by way of example,

the setting 12 may be generally rectangular, circular, oval, orpolygonal as shown having side walls 17, 18, 19, 20, and a bottom wall21.

The side walls 17, 18 are each provided with a gen erally rectangularopening 22 which is of a shape and size to substantially correspond tothe cross section of the flattened end portions 15. The lower edge ofthe openings 22 extend substantially flush with the inner side of thebottom wall 21 and are in line with each other at a position centrallyof the walls 17, 18. The bottom wall 21 has a pair of openings 23therethrough which are positioned adjacent the walls 1'7, 18 and in linewith the openings 22.

In assembling the shank or annulus 11 and the setting 12, the annulus isspread apart sufliciently for the flattened ends 15 to be insertedthrough the openings 22 with the shoulders 16 abutting against the edgesof the walls 17 and 18 (see Figure 5). The ends 15 may now be bentupwardly to be clenched against the adjacent wall portions so as tosecurely clamp the said wall 17, 18 between the ends 15 and shoulders 16in the known manner. The gem or ornament 13 may now be positioned in thesetting 12 and the prongs 14 bent over the edges of the gem 13 to holdthe same in position in the known manner. in bending the ends 15 toclench the same in place, the tool or tools employed (not shown) may beinserted through the openings 23 to engage and bend said ends 15.

As will be seen in Figure 2, the portions 15 of the ring shank extend tonear the upper edge of the setting 12 and are engaged with the lowerside portions of the gem 13. Thus, the portions 15 are additionallyclamped between the walls of the setting 12 and gem 13. This assures asecure binding of the ring elements to each other. Should there be animproper bending or clinching of the portions 15, the gem when being setor secured in place will engage such improperly bent portions 15 andforce the same or complete the bending thereof firmly into properposition.

From the foregoing description it will be apparent that I have discloseda two-piece ring which may be easily assembled and secured to each otherwithout a solder operation. It will be further apparent that the ringafter assembly may be further processed to finish the same ready toreceive the gem.

I claim:

1. A finger ring comprising a gem setting having bottom, side, and endwalls, the upper edges of said side and end walls providing a seat forreceiving a gem, said side walls having an opening therethrough at thelower portion thereof, a split annulus having the end portions thereofflattened inwardly from the outer side thereof, said flattened endportions extending through said openings and bent upwardly in the planeof the annulus about an axis parallel to the flattened end against saidside walls, said openings being of a shape corresponding to the shape ofthe flattened ends to prevent rotation, and a stone engaged with saidend portions to additionally bind said portions securely in place, andfingers on said side and end walls engaging said gem and securing thesame in said setting.

2. A finger ring as set forth in claim 1 wherein said bottom wall hasopenings therethrough through which a tool may be inserted for engagingand bending said fiattened portions against said side walls.
